Language allows us to share our thoughts, ideas, emotions, and intention with others. Over thousands of years, humans have developed a wide variety of systems to assign specific meaning to sounds, forming words and systems of grammar to create languages. Many languages developed written forms using symbols to visually record their meaning. Some languages, like American Sign Language (ASL), are an entirely visual language without the need for vocalizations. Although languages are defined by rules, they are by no means static, and evolve over time.
